--- Comment #26 from David Ing <divirt...@coevolving.com> --- I'm sad to report that resetting the panel to default does not solve the problem. After the first reset, I my usual customization by setting up a second panel on the second monitor (i.e. on the right window edge of the right monitor). The glitch turned up within 10 minutes. Thinking that this glitch might be due to a second panel, I reset again. In the case that it might be causes by a single application having multiple windows (i.e. Google Chrome starts a separate window for Hangouts), I terminated the second window. The glitch didn't happen on the first day, but has on the second day (after suspending the Thinkpad and then resuming the next morning). The only workaround I've found is to reboot the computer. Until then, all I can do is alt-tab between screens. Truly annoying. Are there any other diagnostics that would move resolving the problem along? -- You are receiving this mail because: You are watching all bug changes.
